To allwhomit mag concern: I

Be it known that we, VERNON W. BALZER and JOHN MQK. BALLoU, citizens ofthe United States. residing at Los Angeles, in the countyof Los Angelesand State of California,haveinvented a new and useful Look, of whichthe followingis a specification.

This invention relates to devices for interengagin'g I different members against movement, as in padlocks, door .locks,';safety locks, vault locks, and other similar devices. v )ne of the objects of this inventionis to hold the bolt in such a lock against turning movement.

Another'object is to hold a bolt against shifting movement.

Another object is to hold a bolt against a combined shifting and turning movement.

Another object is to provide abolt Which must be shifted in longitudinal direction before it can be turned for unlocking the device. I

Another object is to provide engaging members. generally called tumblers, for detaining the bolt in its place or normally locking position. i 1

Another object is to provide tumblers so disposed that the bolt may not be shifted in longitudinal direction until all tumblers are properly set. T I

Another object is to provide means for preventing the rotatingmovement of'a bolt I until ashifting movement has been accomplishe'd, tumblers being provided to hold the bolt against shifting movement until all tumblers are properly set. I

i L-inother object is to provide a contact within the lock in coaotive relationto the locking: members of the device. I

Anotherobject is to provide a front. plate selflo'cking to thedevice andasohel'd until the bolt is in releasingposition. 7

Another object is to provide such a lock especially adapted for an automobile lock to be inserted into thewiring system of such automobiles. I Another object 'is to provide misleading means for misleading in the finding of the correct shitting position through or in'relation"to the severaltumblers.

Other objects will appear from the-following description andappen'ded claims as :2 in Fig. 1.

It will. however, easily be unlerstood that the parts may just as Well be madeiof other material as lon and otherwise suitable.

atoneend and with abottom 1 1 at the other end. The bottom 11 is provided With a bore 12 for the shaft orilockpb-olt 14,

with a number of perforations 13 according to the number of projecting ends or lips 15 v p The inner bottom is illustrated in detail in Fig. 3,

showing these projecting or extension; ends on the inner bottom plate 16.

or lips 15 and showingalso apeculiarlyas they are strong enough I shaped core or perforation comprised of practically circularportion ll'i'and the side aosed over the flan 'ed open end o'l'vthe 'c'a's 3 1 ing 9, being provided 'Witha'fiange 20and a bore or hole This plate-isillustratediin detail in end-view in, Fig.2. A sl'eeve22 is extension 18, The 15 and the corresponding perforations 1 3 ser e the purpose or moving Within the-casing "9* hen so disposed,- as scribed later on. A front plate 19 lsgdis- I disposed through the: bore 21 t'or aiturning movement within the front plate 19 and on the bolt or stem 14. The sleeve 22 is provided with a shoulder ring 23 turnably seating against the inside of the front plate 1.9 and forminga shoulder for the tumblers in the device. The further end 24. of the sleeve 22 forms the seating stud on which the several tumblers are turnably mounted. One of the tumblers, preferably the innermost, that is, the one nearest to the end of the seating stud 24, is secured to the stud by riveting or press-fitting or in other similar manners.

Three tumblers are illustrated in the drawing,- but it will easily be understood thati any other number of tumblers may be use The tumbler 25 is nearest the stud end and shown riveted to the end of the stud 24. The securing of this tumbler can easily be accomplished by roughening or knurling that portion of the seat on the stud 24's on which the tumbler 25 is to seat and then tightly pressing the tumbler on this roughened portion. A slight riveting over as indicated at 28 naturally helps and tends to keep the tumbler in its position on the end of the stud 24L.

The outer end 29 of the 22 is pre erably roughened in a similar manner to allow a securino of a dial to this front end.

The one tumbler is naturally secured to the stud 24 so as to allow a free and easy turning and operating of the other tumblers, in this case of the tumblers 26 and 27. The tumblers'26 and 27 then turn and operate easily between the tumbler 25 and the shoulder ring 23 of the sleeve 22, (s will easily be understood.

The shoulder portion 30 on the stem or bolt 14 is also preferably roughened in a similar manner to securely hold the locking member 31. The member 31 is provided with an extension end 32, bent to project practically parallel to the longitudinal axis of the-stem. The front end of the end 32 tance further in the lock. so that the handle 34 on the front end of the stem practically comes to, rest against the front face 35 of outermost point of the lock and the locking member 31 practically comes to rest in or against the bottom 11 of the casing; 9. In

' such locking position, the end 32 of the looking member 31 is withdrawn from the tumblers so that the tumblers can freely turn without influencing the locking part of the device. The locking member 31, being so secured to the stem in the manner described above, is firmly held and disposed within the peculiarly-shaped hole in the inner bottom plate 16, the practically circular portion 31 of the locking member easily passlng through the practically circular portion 17 of the bore in the inner bottom plate, while the end 32 of the locking member partly remainswithin the portion 18 of the bore or perforation in the inner bottom 16, see Figs. 1 and 3. The end 32 prevents in this manner the stem from turning when in such locking, position.

The tumblers are provided with corre sponding perforations 36 to allow the end 32 tothrough the tumblers when the tumblers are set correctly in the combination for unlocking the device. see Fig. 4c. Other perforations 3'? are preferably provided in the tumblers for misleading; in the finding a of the combination of the device.

For operating the tumblers, the tumblers 26 and 27 must naturally be operated by the first tumbler 25, and the siinplcst thing is natiu'ally to have a pin or engaging member in one tumbler for tumbler. ln the drawin the pins 38, 39 and 4-0 serve to transmit the motion from one tumbler to the next one. Corresponding; holes or perforations are naturally provided in the flanges of the tumblers. The pins 38, 39 and are shown and illustrated of shouldered form. the smaller portion fitting in the perforations of the flanges of the tumblers while the larger head portions are disposed between the flanges 41 of the tumblers. The pins naturally-cannot be dislodged when made in this form, since the head portions of the pins can be made just to fit between two adjoining;- flanges of the tumblers while the smaller portions can naturally easily be made to fit tightly and securely in the perforationsof the flanges of the tumblers.the flanges being indicated at 41.

The pins mag-J. however. be made in form of screws. the threaded. portions of the screws to be secured in the perforations of the es 451 and the heads or free end projectin out of the flanges for engaging with the screws in the next adjoining tumblers. Such minor modification need, of course. not be illustrated.

A. dial is secured to the front end of the sleeve 22 for operating the tumblers and actuating: the nextbolt 14 are above the inner bottom 16 so that the bolt 1 with the contact member 46 can be turned to engage with the corresponding contact members in the insulating block 53. As long as the locking member on the stem or bolt 14: is in the position that the locking member is engaged by the inner bottom, the bolt can naturally not be turned and the switch cannot be operated. In such locking position, the tumblers are just turned to some extent that the locking end 32 of the locking member cannot move in the direction towards the front that is through the tumblers.

Any number of perforations can naturally be provided in the flanges of the tumblers, so that the pins 38, 39 and 4.0 may be disposed in different combinations. One tumbler being only turned, moved, or operated by the engagement of the pin in one tumbler with the pin in the next nearest tumbler, it naturally follows that a changing of the pins to difierent positions in the different tumblers necessitates different movements of the tumblers before the next adjoining tumblers are moved or r co-operating member to pass fully through the full-sized and only to the extent of the thickness of the tumbler through the less than full-sized passages.

2. In a look, a casing, tumblers turnably disposed in the casing, a locking bolt turnably and shiftably' disposed through the center of the tumblers, the tumblers having full-sized and less than full-sized passages parallel to their central axis, the locking bolt having a locking member projecting sidewise and extending parallel to thelongitudinal axis of the bolt, the front termination of the locking member being of a shape to easily pass through the full-sized passages in the tumblers and adapted to pass through the less than-full-sized passages of the tumblers to the extent of the thickness ofone tumbler only, and means to bring the fullsized passages of all tumblers into alignment so that the locking member of the locking bolt can pass to unlock the lock.

In a lock, tumblers having full-sized and less than full-sized passages,- and a locking bolt having means to pass through the full-sized passages of the tumblers fully while only able to pass through the less than full-sized passages of the tumblers to the distance equal to the thickness of one tumbler. J

41. In a lock, a'casing, tumblers in the easing having each a central perforation, a dial operatively connected with the tumblers disposed on the outside of the casing, a locking bolt turnablyand shiftably disposed through the center of the dial and the tumblers, a locking member pro-jeoting'radially from the bolt and extending parallel to the axis of the bolt spaced from the bolt, the tumblershaving full-sized and less than fulL sized passages parallel to the central perforations, the front termination of the looking member being of a shape to easily pass through the full-sized passages when all tumblers are properly aligned the dial and adapted to pass through the less-than full sized passages of the tumblers to the extent of the thickness of one tumbler only when the tumblers are not in proper alignment, and means for holding the bolt against turning movements as long as not all tumblers are properly aligned by the dial. I In testimony that we claim the foregoing as our invention we have signed our names in the presence of two subscribing witnesses.
